- Short: Library to ctrl the MC68K MMUs, early alpha
- Uploader: thor@math.tu-berlin.de (Thomas Richter)
- Author: thor@math.tu-berlin.de (Thomas Richter)
- Type: util/libs
- Requires: Os 2.04
- Version: 0.05
-
- -----------------------------------------------------------------------------
-
- Release 0.05
- ------------
-
- -Fixed a bug in the context management, memory property setup
- routine. Due to a typo, one register was assigned in the wrong
- way and messed up the routine. Just the joy of assembly! Sigh.
- "NUTS" seems to work flawlessy, though.
- Thanks to all the testers, locating and fixing this bug was
- just a matter of ten minutes.
-
- -----------------------------------------------------------------------------
- Warning: This is "work in progress", it's by no means complete.
-
- I'm in the urge need for testers and co-authors. Especially MC68040 and
- MC68060 systems are very welcome for testing.
-
- Please check the "ReadMe" in the archive for details how to contact me.

-
- Purpose and goal of this library:
-
- The mmu.library is a planned basis for MMU (memory management) related
- functions the MC68K family can perform. Up to now certain hacks are available
- that program the MMU themselves (Enforcer,CyberGuard,GuardianAngle,SetCPU,
- Shapeshifter,VMM,GigaMem...).
- It's therefore not unexpected that these tools conflict with each other.
- There's up to now no Os support for the MMU at all - the gap this mmu.library
- is planned to fill.
-
- The goal is to provide a basis of functions to address and program the MMU in
- a hardware independent, Os friendly fashion. Hence, a future version of the
- Enforcer will work together with virtual memory, and others.
-
- The mmu.library is also the basis for a virtual memory project, the
- memory.library. Even though the mmu.library does not provide virtual memory
- itself, it builds the basics to allow an easy implementation and to avoid the
- hacks required by other implementations so far.
-
- For the design details of the mmu.library, consider reading the autodocs in
- this archive. Everything is still VERY preliminary, there's still room for
- changes and suggestions.
-
- ------------------------------------------------------------------------------
-
- This distribution contains the full sources written so far, the documentation
- and some C sample sources how to use the library, as well as the includes
- and autodocs written so far. Check the ReadMe for details. Even if you're not
- a developer, you could help me a lot by running a test program on your
- computer and sending me the results. Just "CD" into the unpacked archive
- and enter "MMUScan" and "PrintTTx", and send me the results. That's up to
- now all.
-
- ------------------------------------------------------------------------------
- The mmu.library development group:
-
- This is a loose, non-commercial group of developers that support the
- mmu.library by their work. If you want to join, I'll setup a mailing list
- for the interested.
